Estudo anatômico e morfométrico dos folículos testiculares de algumas espécies de Triatominae (Hemiptera: Reduviidae)

Abstract: Os folículos testiculares nas ordens dos insetos, vêm demonstrando papel relevante sob o ponto de vista da Sistemática e Filogenia. Nos triatomíneos, os folículos testiculares são em número de sete, sendo que o comprimento e a espesura variam consideravelmente entre os gêneros, e pouco entre as espécies. Verificou-se que em Rhodnius spp existem dois folículos longos e grossos e cinco curtos e fuinnos; em Triatoma spp existem dois longos e finos, dois médios e grossos e três curtos e finos; e em Panstrongylus s… Show more

“…The number of testicular follicles varies from four to six. It is different from those found in Pentatomidae , but similar to Triatominae (Gonçalves et al 1987), indicating that the number of testicular follicles may vary among Heteroptera families. The testicular follicles have the following regions: the growth zone, where the spermatogonia increases allowing occurrence of mitoses and differentiation into spermatocytes; the maturation zone, where meiosis takes place originating spermatids; and the differentiation zone, where spermatids are extended to form the spermatozoa ( Fig.…”

“…The morphology of the salivary glands and proportions between the testicular tubes aid on the generic differentiation, and the structure of male genitalia can be used for the specifi c diagnosis, as demonstrated in Lent and Wygodzinsky ( 1979 ), Gonçalves et al ( 1987 ), and Santos et al ( 1997 ). These characters, in association with the study of live specimens when available, and the use of molecular, cytogenetic, morphometric, and histochemical tools provide support for the discovery of cryptic species and for the development of phylogenetic analysis (Jurberg 2003 ;Galvão 2003 ).…”

“…In triatomines the number of follicles is always seven. However, the size of the follicles allows the characterization of the genera Rhodnius, Psammolestes, Panstrongylus, Triatoma, Meccus and Mepraia [6][7][8][9] (Table 1).…”
